Customizing PDF output

Customizing PDF output Example of PDF output customization with a custom transformation type. Create a new plug-in directory com.example.print-pdf into DITA-OT plugins directory. Create a plug-in configuration file plugin.xml, declare the new transformation type print-pdf and dependencies. <?xml version='1.0' encoding='UTF-8'?> <plugin id="com.example.print-pdf"> <require plugin="org.dita.pdf2"/> <feature extension="dita.conductor.transtype.check" value="print-pdf"/> <feature extension="dita.transtype.print" value="print-pdf"/> <feature extension="dita.conductor.target.relative" file="integrator.xml"/> </plugin> Add an Ant script integrator.xml to define the transformation type. <?xml version='1.0' encoding='UTF-8'?> <project name="com.example.print-pdf"> <target name="dita2print-pdf.init"> <property name="customization.dir" location="${dita.plugin.com.example.print-pdf.dir}/cfg"/> </target> <target name="dita2print-pdf" depends="dita2print-pdf.init, dita2pdf2"/> </project> Add a cfg/catalog.xml file to take custom XSLT stylesheets into use. <?xml version="1.0" encoding="UTF-8"?> <catalog prefer="system" xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> <uri name="cfg:fo/attrs/custom.xsl" uri="fo/attrs/custom.xsl"/> <uri name="cfg:fo/xsl/custom.xsl" uri="fo/xsl/custom.xsl"/> </catalog> Add attribute and variable overrides to cfg/fo/attrs/custom.xsl <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">  <xsl:variable name="page-width">210mm</xsl:variable> <xsl:variable name="page-height">297mm</xsl:variable> </xsl:stylesheet> Add XSLT overrides to cfg/fo/xsl/custom.xsl <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fo="http://www.w3.org/1999/XSL/Format" version="2.0">  <xsl:template match="*[contains(@class,' topic/fig ')]"> <fo:block xsl:use-attribute-sets="fig"> <xsl:call-template name="commonattributes"/> <xsl:if test="not(@id)"> <xsl:attribute name="id"> <xsl:call-template name="get-id"/> </xsl:attribute> </xsl:if> <xsl:apply-templates select="*[contains(@class,' topic/title ')]"/> <xsl:apply-templates select="*[not(contains(@class,' topic/title ') or contains(@class,' topic/desc '))]"/> <xsl:apply-templates select="*[contains(@class,' topic/desc ')]"/> </fo:block> </xsl:template> </xsl:stylesheet> Add variable definition file cfg/common/vars/en.xml for English to override generated text. <?xml version="1.0" encoding="UTF-8"?> <vars xmlns="http://www.idiominc.com/opentopic/vars">  <variable id="Ordered List Number"><param ref-name="number"/></variable>  <variable id="Unordered List bullet">—</variable> </vars>

The plug-in directory should have the layout and files:

com.example.print-pdf/ cfg/ common/ vars/ en.xml fo/ attrs/ custom.xsl xsl/ custom.xsl catalog.xml integrator.xml plugin.xml

Run integration process to install the plug-in and take the print-pdf transformation type into use.
